Description

The present invention relates to an electronic keyboard instrument that can play a keyboard with a specific instrument tone color in an electronic keyboard instrument having an opening / closing lid at the front of a musical instrument body.
If a specific instrument tone is used as a standard instrument tone of a keyboard instrument, it is suitable for playing by a natural instrument player such as a pianist.

Keyboard instruments include natural musical instruments (acoustics) and electronic sound sources. Both are musical instruments that play the keyboard, but the keyboard players were specialized in pianists and electronic keyboard instrument players.
However, recent electronic keyboard instruments have a piano action mechanism, which makes it possible to obtain a key touch similar to that of a piano. Therefore, even if the pianist played the electronic keyboard instrument, the uncomfortable feeling in performance was reduced.
In addition, parents who want to learn keyboard instruments often have their children choose an electronic keyboard instrument that is easy to play so that the child can select either a pianist or an electronic keyboard instrument player in the future. Yes.

However, in an electronic keyboard instrument, a musical instrument tone color is arbitrarily set by a setting operator. Therefore, when the pianist or the parent tries to start playing the piano, if the tone is set to a tone other than that of the piano, he / she does not know what operation should be used to make the piano tone. Not only instrument sounds but various settings such as volume cannot be set freely. Further, unlike the appearance of a natural keyboard instrument, the electronic keyboard instrument is anxious to the pianist and parent because a number of setting operators are arranged on the operation panel unit.
Therefore, when a pianist performs on the stage, the piano must be brought to the stage, and parents cannot play electronic keyboard instruments at home.
Because of these various circumstances, it is said that it is desirable to be able to perform the same performance as an acoustic keyboard instrument without operating a large number of setting operators arranged on the operation panel in an electronic keyboard instrument. There is a request.
In addition, depending on the user, there may be a case where it is desired to perform with any instrument tone color that is always determined other than the standard instrument tone color of a natural keyboard instrument. In this case, there is no need to operate or view many setting operators arranged on the operation panel.

In view of this, it is conceivable that the electronic keyboard instrument is initially set to the tone (piano tone) of the natural keyboard instrument when the power is turned on. However, when the power is turned on, the instrument tone color designation data used in the previous performance is backed up and read out, or the instrument tone color designation data set at the time of factory shipment is read out. Therefore, the tone of the natural keyboard instrument is not always specified.
Some conventional electronic keyboard instruments have a keyboard lid that covers the front portion of the electronic musical instrument body (see Patent Document 1). Therefore, it is conceivable to set the tone of a natural keyboard instrument in relation to the operation of opening the keyboard lid.

On the other hand, in an electronic musical instrument having a shape imitating an acoustic piano, a timbre parameter supplied to a musical tone generation circuit is changed according to the open / close state of an upper lid (see Patent Document 2). However, it is intended to imitate the acoustic characteristics when the upper lid of the acoustic piano is opened and the acoustic characteristics when the acoustic piano is closed, and does not set the instrument tone by opening and closing the lid.
In addition, a keyboard lid capable of partially covering only the central part is arranged in the central part of the keyboard of the electronic musical instrument, and when this central part is covered, the keyboard performance area is divided into left and right keyboards. Thus, there is known one that can change the tone of the left and right keyboards (see Patent Document 3). However, the instrument tone of the electronic musical instrument itself is not set by opening and closing the lid that covers the entire keyboard.
No. 7-49511 JP-A-10-91154 No. 7-20715

Further, it is possible to perform the keyboard with the appearance similar to that of a natural keyboard instrument in which the operation panel portion is not exposed.
Depending on how the lid is opened, the settings can be made exactly the same as those of conventional electronic keyboard instruments, so that any instrument tone that was backed up when the power was turned off can be selected. .

FIG. 1 is a block diagram illustrating a functional configuration of an electronic keyboard instrument according to an embodiment of the present invention. For example, in FIG. 2 to be described later, the electronic keyboard instrument includes a musical instrument main body 11 in which a keyboard part (keyboard unit 20) and an operation panel part 21 are mounted on a front part F, and an open / close lid that opens and closes the front part F ( A structure with a keyboard lid 16) is provided.
Arbitrary instrument timbre designating section 1 designates an arbitrary instrument timbre by operation of an instrument timbre designation operator, as in the prior art, and instrument timbre setting section 3 designates the designated instrument timbre as the instrument timbre of this electronic keyboard instrument. Set as. The tone generator unit 6 generates musical tone of musical instrument tone color set in the instrument tone color setting unit 3 in accordance with the performance operation of the keyboard unit.

The specific musical instrument tone color designation unit 4 detects the operation of the specific musical instrument tone color designation operator.
The specific instrument tone color setting unit 2 sets specific instrument tone color designation data in accordance with the operation of the specific instrument tone color designation operator 4. For example, one of the first and second specific instrument tone color designation data is selected according to the user, and the selected one is set and stored as specific instrument tone color designation data.
As shown in the figure, the specific instrument timbre setting unit 2 may be set to one selected from a plurality of instrument timbres (specific instrument timbre group) determined in advance as specific instrument timbre candidates. Alternatively, any instrument tone color that can be set as the sound source of the electronic keyboard instrument may be set.

Specifically, the specific instrument tone color can be set when necessary, for example, by a user operation before or during the performance.
Further, in an electronic keyboard instrument that can be registered by the user, the specific instrument timbre designation unit 4 may be a means for detecting an operation of a specific instrument timbre designation operator that sets a specific instrument timbre at the time of user registration. The specific instrument timbre setting unit 2 requires the specific instrument timbre designation data at the time of user registration (including the time of registration update) or afterwards in accordance with the operation of the specific instrument timbre designation operator. Set this to

Here, the instrument timbre means a timbre reminiscent of a specific instrument, whether it is a timbre of a natural instrument or an electronically synthesized timbre.
As the first and second specific instrument timbres, for example, standard instrument timbre candidates that can be said to be standard instrument timbres for natural (acoustic) keyboard instruments are fixedly prepared. Specifically, two timbres of a grand piano and a harpsichord (hereinafter referred to as a harpsichord) are prepared. An organ (lead organ or pipe organ) tone may be prepared as the third specific musical instrument tone color. However, in the case of a pipe organ, since the tone color is variable, at least one tone color is specified and set.
As described above, the specific instrument timbre should generally be the standard instrument timbre of a natural keyboard instrument. However, since it is assumed that the user plays with any instrument tone other than the standard instrument tone of the natural keyboard instrument, it is possible to select any instrument tone that is always determined as a specific instrument tone. Good.

The lid open state detection unit 5 detects the lid open state of the opening / closing lid described above. The opening / closing lid opens a part of the front part (front part F in FIG. 2) including the keyboard part (in other words, exposes a part of the front part) and covers the operation panel part (21 in FIG. 2). It is detected whether or not a “predetermined state”. This “predetermined state” is a state that exhibits the appearance of a natural keyboard instrument.
It should be noted that the entire front part of the instrument body, that is, a state where both the keyboard part and the operation panel part are opened (exposed) may be detected. This state is a state in which the appearance of the electronic musical instrument is completely exhibited.

When the lid opening state detection unit 5 detects the “predetermined state” described above, the instrument tone color setting unit 3 selects the specific instrument tone color designation data set by the specific instrument tone color setting unit 2 described above. On the other hand, when the other state (for example, the state in which both the keyboard unit and the operation panel unit described above are opened) is detected, the arbitrary instrument tone color designation data designated by the arbitrary instrument tone color designation unit 1 is stored in the electronic keyboard instrument. The musical instrument tone color is set as the musical instrument tone color generated by the sound source 6.
Here, at the time of initial setting at the time of power activation, the instrument tone color setting unit 3 is set with arbitrary instrument tone color designation data. For example, when the backup is set to ON, this arbitrary instrument tone specification data becomes an arbitrary instrument tone that was set during the previous power-on and was retained even when the electronic keyboard instrument was turned off. If is set to OFF, the instrument tone set at the factory is used. This arbitrary musical instrument tone color is arbitrarily changed by the user's tone color designation operation while the power is on.
When a specific instrument tone color is fixed to one (for example, a grand piano), the above-described specific instrument tone color setting unit 2 and the specific instrument tone color designating unit 4 are not necessary.

In the above description, only the instrument tone color has been described as an item to be set for the electronic keyboard instrument.
However, the reverb type, depth, effect type, and depth thereof may be set in conjunction with the instrument tone color setting in accordance with the instrument tone color setting. In addition to instrument sounds, there are many types of setting data that can be set for electronic keyboard instruments. For example, dual performance function setting data, keyboard split performance function setting data, key touch response function setting data, output volume setting data, reference pitch setting data, temperament setting data, pedal function setting data, etc. is there.
Therefore, when the lid open state detected by the lid open state detection unit 5 is a predetermined state, the setting means for this setting item is designated by the designation means for each setting item for at least one setting item other than the instrument tone color. Specific designation data may be used as setting data for the electronic keyboard instrument instead of the arbitrary designation data.
As the specific designation data, for example, by using standard designation data as a natural keyboard instrument, the performance of the natural keyboard instrument can be expressed.

For the setting means for at least one setting item other than the instrument tone color, the specific designation data is selected from a plurality of designation data (specific designation data group) determined in advance as candidates for the specific designation data May be set, or data arbitrarily selected from all specified data that can be set for a sound source or the like may be set.
Note that when the specific designation data is fixed to one, those corresponding to the specific musical instrument tone color setting unit 2 and the specific musical instrument tone color designation unit 4 described above are unnecessary.

FIG. 2 is a right sectional view for explaining the structure of the embodiment of the present invention. This is an improvement based on the premise of the electronic keyboard instrument described in Patent Document 1.
The upper part of the instrument body 11 is between a pair of left and right side plates 12 (lower part of the instrument body) extending to the lower floor, a bottom plate (shelf plate) 13, a back plate 14, an upper plate 15, a keyboard lid 16, and It is formed in a box shape surrounded by the mouth stick 17.
A keyboard unit 20 in which a keyboard row of a number of white keys 19a and black keys 19b is arranged on a keyboard frame 18 is placed in front of the box.

The operation panel unit 21 covers the upper surface of the rear end of the keyboard unit 20 and is provided with push buttons for various settings, a rotary volume, an electrical component 22 such as a liquid crystal display, a spacer 23, and a partition unit 24. Reference numeral 25 denotes a printed circuit board.
Of the push button switches for various settings described above, the instrument tone color designation switch (operator) 221 is provided closer to the keyboard side. A plurality of instrument tone color designation switches 221 are provided in the key arrangement direction, such as 221-1, 221-2, 221-3,..., For example, marimba, brass, guitar, etc. can be selected. It has become. The instrument tone color designation switch 221 includes one for setting an instrument tone color such as a grand piano or a harpsichord as a specific instrument tone color designation operator.
A mounting member 222 is fixed to the inner side surfaces of the pair of left and right mountain plates 26 by a set screw 27. The operation panel unit 21 is disposed with both ends thereof fixed to the mounting member 222 with screws 223.
The upper surface 26a of the front half portion of the deck 26 functions as a slide guide that supports and slides the side end of the keyboard lid 16 when the keyboard lid 16 is opened and closed.

A keyboard lid hanging piece 28 having a grip 29 is attached to the front portion of the keyboard lid 16, and an auxiliary metal fitting 30 is attached to the rear portion thereof. A rotating shaft 32 is pivotally supported on the bracket 31 of the auxiliary metal fitting 30 over the left and right sides of the electronic keyboard instrument, and pinions 33 are fitted in the vicinity of the shaft end of the rotating shaft 32, respectively.
On the other hand, a rack 34 that meshes with the above-described pinion 33 is provided on the upper side surface of the rear half of the pair of left and right piles 26, and guide grooves 35 are provided on the upper outer side of the rack 34. Both shafts of the rotary shaft 32 are slidably fitted in both guide grooves 35.
The rack 34 and the guide groove 35 are provided over the entire range in which the keyboard lid 16 can be opened and closed.

The bracket 31, the rotation shaft 32, the pinion 33, the rack 34, and the guide groove 35 described above are the same as those in the conventional device, and constitute a lid opening / closing device 36 for the keyboard lid 16.
When the pinion 33 moves forward on the rack 34 and the rotating shaft 32 comes into contact with the front end of the guide groove 35, the keyboard lid 16 moves to the mouth bar 17 and covers the keyboard unit 20.
From this state, the grip portion 29 is lifted, the keyboard lid hanging piece 28 is placed on the upper surface 26a of the front half of the pile 26, the keyboard lid 16 is slid rearward, and the rotary shaft 32 is the rear end of the guide groove 35. The keyboard lid 16 is housed in the rear part of the instrument body 11 when it comes into contact with the instrument body 11. As a result, the keyboard surface of the white key 19a and the black key 19b of the keyboard unit 20, the partition part 24, and the operation panel part 21 are exposed open.
Reference numeral 37 denotes a position where a locking mechanism described later with reference to FIG. 4 is installed.

3 is a right-side cross-sectional view in which the structure shown in FIG. 2 is partially enlarged.
In the figure, parts similar to those in FIG.
In the conventional apparatus, it is assumed that the keyboard cover 16 performs with the keyboard cover 16 completely stored and the entire front part of the instrument body 11 opened as shown in the second state in the figure. It was.
On the other hand, in the embodiment of the present invention, as shown in the first state in the figure, the keyboard lid 16 opens only a part of the front part including the keyboard unit 20 and covers the operation panel unit 21. The performance can be performed even in a predetermined state (intermediate position of the lid). At this time, the partition unit 24 partitions the keyboard unit unit 20 side and the operation panel unit 21 side together with the keyboard lid hanging piece 28.

In this first state, for example, a performance similar to that of a natural keyboard instrument can be performed.
That is, the specific instrument tone color set by the specific instrument tone color designating unit 5 shown in FIG. 1 is selected. In the specific example, the tone of the natural keyboard instrument is selected. The lid open state detection unit 5 detects whether the keyboard lid 16 is in the first state or the second state by detecting the lid open state.
When the keyboard lid 16 is in the first state, for example, an arbitrary portion of the keyboard lid 16 or an arbitrary portion of the keyboard lid hanging piece 28 integrated with the keyboard lid 16 is arranged at a predetermined position of the instrument body. It is detected that the actuator is pushed or the optical path of the transmissive or reflective photosensor is interrupted.
For example, if a photo sensor is provided on the upper side surface of the partition portion 24 and the keyboard lid hanging piece 28 is detected, the predetermined state can be accurately detected. In addition, a sensor that switches in conjunction with the movement of the leaf spring of FIG. 4 described later may be provided to detect the first state.
The first state and the second state described above are the opened state of the keyboard cover 16 in the first use state and the second use state. In any other open state, it is arbitrary whether a specific instrument tone color or an arbitrary instrument tone color is designated or disabled.

When the specific instrument timbre specifying unit 4 shown in FIG. 1 specifies a specific instrument timbre by the specific instrument timbre specifying operator, the specific instrument timbre specifying operator is used when the keyboard cover 16 is in the first state. What is necessary is just to provide in the exposed part.
More specifically, in the keyboard unit 20, the key unit 20 is provided on a portion (for example, a beat tree) that is provided alongside a visible portion of the key (a portion of the white key 19 a and the black key 19 b that is not hidden by the partition portion 24). That's fine.

The specific musical instrument tone color designating operator may be provided on the bottom and bottom sides of the electronic keyboard instrument. A specific instrument tone color may be set for the electronic keyboard instrument using a remote control device (remote control terminal) or using an external device via a communication network.
The specific musical instrument tone color designation unit 4 shown in FIG. 1 is arbitrarily set from among a plurality of musical instrument tone color designation switches 221 (2211-1, 221-2, 221-3,...) On the operation panel unit 21. It is possible to specify and set an arbitrary instrument tone by selecting a corresponding instrument tone by selecting an operator or by selecting a combination of a plurality of limited setting operators such as a numeric key switch. Or you may.

Since the operation panel unit 21 has a protruding portion 21a that rises at the same height or higher position as the electrical component 22 from the rear to the upper side of the region where the buttons of the electrical component 22 are arranged, the keyboard cover 16 is located at the rear. When housed, the gap between the keyboard lid hanging piece 28 and the operation panel unit 21 is reduced.
Further, since the partition portion 24 is provided in front of the operation panel portion 21 at the same height or higher position as the electric component 22 described above, the keyboard lid hanging piece 28 is in the second state described above. And the partition 24 become smaller.
Since this partition part 24 partitions the keyboard unit part 20 side and the operation panel part 21 side, it is a design accent.
Further, the bottom surface of the lower portion of the partition portion 24 is close to the upper surface of the white key 19a in the non-key-pressed state, and the front surface of the lower portion is close to the rear end surface of the black key 19b in the non-key-pressed state.

Furthermore, the partition unit 24 includes a key press guide display panel provided with a plurality of visual display means, for example, light emitting diodes (LEDs) 41, corresponding to the white keys 19a and the black keys 19b of the keyboard unit unit 20. You may also use it.
That is, the keyboard lid 16 is provided to the control unit of the electronic keyboard instrument by the key depression guide function for guiding the depression of each key by turning on and off the light emitting diode 41 and the lid open state detection unit 5 shown in FIG. When it is detected that the second state is detected, the execution instruction of the key pressing guide display function described above is validated, and when it is detected that the keyboard cover 16 is in the first state, the key pressing is performed. Even if there is an instruction to execute the guidance display hand function, a key depression guidance display function invalidating function for invalidating the guidance display hand function may be provided.

  As a more specific structure, the individual light emitting diodes 41 are inserted and installed in the respective recesses 24 a from the back surface of the partition portion 24. The partition portion 24 is formed of a translucent light-transmitting material so that the light-emitting diode 41 itself is difficult to see in the light-off state, and the light of the light-emitting diode 41 is visible in the light-up state. In this way, it is possible to prevent the appearance of the electronic keyboard instrument from the appearance by observing the plurality of light emitting diodes (LEDs) 41 in the first state.

The light emitting diode 41 is wired on the printed circuit board 25b, and is connected to the printed circuit board 25a on the operation panel side by a jumper line or the like. The printed circuit boards 25a and 25b are integrally formed, the board of the jumper line portion is removed and divided, and the jumper line is bent at the root part.
Instead of the visible display using the light emitting diode 41 described above, a key press display panel may be used as a visible display means, for example, a liquid crystal display panel.

In the first state of the keyboard lid 16 described above, since the keyboard lid 16 is in the half-open intermediate position, the keyboard lid 16 easily moves back and forth with the conventional lid opening / closing structure. Therefore, it is not possible to play the keyboard while maintaining the first state stable. Therefore, a locking mechanism K for the keyboard lid 16 is provided.
FIG. 4 is a partial structural diagram for explaining the locking mechanism K provided at the position 37 shown in FIG.
In the figure, the same reference numerals are used for the same parts as in FIGS.
51a and 51b are hollow step portions provided on the front and rear sides of the outer side surface of the left mountain plate 26, and the back wall portion of the guide groove 35 is notched between the hollow step portions 51a and 51b.
A bent strip-shaped leaf spring 52 straddling the stepped portions 51a and 51b is fixed to the stepped portion 51a with one end 52a by a mounting screw 53, and the other end 52b is formed into a stepped portion 51b with elasticity. It is energized.
An intermediate portion of the leaf spring 52 is a locking recess 52c that protrudes in the direction of the left and right outer sides of the instrument body, and forms an intermediate stable position.

The crests on the front side and the back side of the recess 52c are crests that protrude in the direction of the center of the instrument body. The keyboard lid locking mechanism K described above may be provided in a pair of left and right, or any one of them.
When the keyboard lid 16 is pushed in the lid opening direction from the lid closed state to the first state, the shaft end 32a gets over the front mountain and is fitted into the recess 52c.
The shaft end 32a is caught and locked in the recess 52c, and is prevented from moving back and forth. Since the recess 52c has a smooth inclination, the player can move again if the player applies extra force to the keyboard lid 16.
When the keyboard cover 16 is pushed further back from the first state, the shaft end 32a gets over the rear peak and comes into contact with the end of the guide groove 35. At this time, the keyboard cover 16 is in the second state and fully opened.
Also when returning to the direction which closes a lid | cover, the axial end 32a gets over the back peak part, and fits into the recessed part 52c.

When the keyboard cover 16 is in the first state, it is necessary to accurately match the position where the shaft end 32a fits into the recess 52c. Therefore, the screw 53 is screwed into a nut (not shown) through an adjustment long hole and a hole provided in the leaf spring 52 so that the fixing position of the leaf spring 52 can be adjusted in the front-rear direction, and the leaf spring 52 is fixed. .
Reference numeral 54 denotes a screw hole, which is for a tapping screw for fixing the left ridge plate 26 to the left side plate 12 of FIG.

Part).
The setting data in the current buffer is rewritten by operating the setting operator. The contents of the current buffer after rewriting are saved in the memory to be backed up even when the power is turned off when the backup of the setting data is set to ON.
A detection circuit 67 detects the operation of the lid opening / closing position detection switch unit 65 and the operation element 66. Reference numeral 68 denotes a display circuit. Reference numeral 69 denotes a display unit, which is a display unit such as a liquid crystal display unit disposed on the operation panel unit 21 or a light-emitting diode 41 for key press guidance.

Reference numeral 70 denotes a sound source unit. A sound source dedicated integrated circuit or DSP (Digital Signal Processor) is used. Reference numeral 71 denotes a DSP. The tone signal generated by the sound source unit 70 is supplied with a reverb or effector effect in the DSP 71, supplied to the sound system 72, amplified, and output to a speaker.
73 is an external device, and 74 is a communication interface. The external device 73 is, for example, an electronic music device such as a MIDI keyboard, a personal computer having a sequencer function, or the like.
An external device 73 connected to the apparatus via a MIDI cable, RS232C, USB (Universal Serial Bus), IEEE1394 or the like outputs performance information such as a MIDI message to the apparatus or inputs performance information from the apparatus.

The CPU 62 uses the RAM 63 as a work area, reads out a control program stored in the ROM 64 to the RAM 63, detects an operation event of the lid open state detection switch 65 and the operation element 66, displays control for the display unit 69, etc. Control parameters based on setting data such as timbre setting data stored in the current buffer of the RAM 63 are transferred to the tone generator 70 and the DSP 71 to control them, and an operator (keyboard) The sound source unit 70 and the DSP 71 are controlled in accordance with performance data obtained from 66 and the like, and a function of outputting a musical sound signal from the sound system 72 is realized.

FIG. 6 is a flowchart for explaining the operation of the embodiment of the present invention shown in FIG.
FIG. 6A is a main flowchart, and FIG. 6B is a flowchart of interrupt processing.
FIG. 6A shows a hidden power source provided in a place where the keyboard cover 16 shown in FIG. 2 is opened from the closed state or the instrument body is inconspicuous with the power plug of the electronic keyboard instrument inserted into the outlet. Start by either turning on the switch.

  In S81, the initial setting at the time of power-on may be performed in the same manner as a conventional electronic keyboard instrument. For example, if the backup ON / OFF data saved in ROM (flash ROM) 64 etc. is ON, the setting data that was saved in the same way and was backed up before the last power off, if OFF The setting data at the time of shipment from the factory is written into the current buffer, and various setting parameters corresponding to the setting data are set in the corresponding block or the function realizing means realized by the CPU 62.

In the following processing, the flag PW is used. This flag PW represents the use mode, and PW = 0 when the power supply is being prepared or the power supply is being processed, and PW = 1 when the use mode is 1 (a specific instrument tone, for example, a standard instrument tone of a natural keyboard instrument). And PW = 2 in use mode 2 (arbitrary instrument tone). The usage mode 1 is a usage pattern intended to approximate the performance of a natural keyboard instrument, and the usage mode 2 is a usage pattern of a general electronic keyboard instrument.
In S82, the lid open state (lid position) is detected. When the lid position is the intermediate position (first state in FIG. 3), the process proceeds to S83.
In the process of moving the keyboard lid 16, it is better to be in the intermediate position for a predetermined time or longer so as not to immediately enter the use mode 1 when passing the intermediate position temporarily. Good.
In S83, if PW = 1, the process proceeds to S84 to set PW = 1, and in S85, the current musical instrument tone color setting data stored in the current buffer is set as data specifying the grand piano (first specific musical instrument tone color). Designated data), and the process proceeds to S86. If PW = 1 already, the process immediately proceeds to S86.

  In S85, the current setting data stored in the current buffer other than the instrument tone color setting data is also set to specific designation data, for example, standard designation data that is close to the performance of a natural keyboard instrument. For example, data specifying a standard volume value is set as the volume setting data (originally, the volume is adjusted by the master volume, but is set to the standard volume value regardless of the position of the master volume), and automatic function setting data Designate OFF as an automatic function for electronic musical instruments (for example, a dual function, a split function, etc.), and set all to OFF.

Next, the process proceeds to S86, and it is determined whether or not there has been a selection operation for designating a specific instrument tone color. When the second specific instrument timbre designation data is selected, the process proceeds to S87, the current instrument timbre setting data is set as data specifying the harpsichord (second specific instrument timbre designation data), and the process proceeds to S89. . On the other hand, when the first specific instrument tone color designation data is selected, the process proceeds to S88, and the current instrument tone color setting data is set as the data (first specific instrument tone color designation data) for designating the grand piano. Proceed with the process.
If there is no selection operation, the process immediately proceeds to S89.
S89 and S90 are keyboard performance processes. When there is a change in the operation state of the keyboard operator in S89, the process proceeds to S90, and according to the current various setting data stored in the current buffer. Keyboard processing such as musical tone generation / mute processing is performed, the sound source 70 (FIG. 5) is controlled, and the process returns to S82. In the case of an electronic musical instrument keyboard having a pedal keyboard or pedal, these operation detections and corresponding processing are also performed.

On the other hand, when the keyboard cover 16 is in the fully open position (second state in FIG. 3) in S82, or not in the closed position (state in FIG. 2) or the intermediate position (first state in FIG. 3), The process proceeds to S91. If PW = 2 is not yet reached, the process proceeds to S92 to set PW = 2, and the process proceeds to S93. If PW = 2 already, the process immediately proceeds to S93.
In S93, it is determined whether or not there is an operation event by an operator other than the keyboard used in use mode 2. If there is an operation event, the process proceeds to S94, and if not, the process proceeds to S89 already described.

In S94, for example, if it is an operation event of an instrument tone color specifying operator, the instrument tone color specifying data corresponding to the operator is set as the current instrument tone color setting data. Set the characteristics of the low-pass filter, equalizer characteristics, reverb characteristics, effect characteristics, etc.
If the operation event is a volume operator, the volume designation data corresponding to the operation is set as volume setting data. If it is an operation event of another operation element, designation data corresponding to the operation is set as setting data.
Thereafter, the process proceeds to the keyboard performance of S89 and S90 already described.

When the keyboard cover 16 shown in FIG. 2 is moved to open the operation panel unit 21 (second state) and the keyboard performance is being performed in the use mode 2, the instrument tone color designating operator 221 is performed in S93 and S94 described above. The instrument tone can be changed. Here, when the keyboard cover 16 is moved to the predetermined state ( first state) shown in FIG. 2, the process proceeds from S82 to S83, and the use mode 1 is set.
As a result, even if the instrument tone color is changed in the first use mode 2, the changed instrument tone color is reset and easily reset to a specific instrument tone color.

Next, in S82 described above, when the lid position is the lid closed position, the process proceeds to S95. This is a process when the lid is closed again.
In S95, it is determined whether or not PW = 0. If not 0, the process proceeds to S96 to set PW = 0, and in S97, preparation for power supply termination (preparation for terminating power supply) is performed.
In S97, the current setting state is returned to the initial setting state at the time of power-on performed in S81. Accordingly, the instrument tone color setting data and other setting data that have been manipulated and changed in the use mode 1 are returned to the initial setting state when the power is turned on while the power is on.
However, when the backup is set to ON and the setting data set in S94 is the first specification that has already been backed up, the initial setting state is set according to the changed instrument tone color setting data and other setting data. Has already been changed.
In S98, for example, it is determined whether or not a predetermined time of 3 seconds has elapsed. If not, the process returns to S82.

In the processing of S97 and S98 described above, the current setting data and setting parameters are initially set when the usage mode 1 is entered as a result of accidentally placing the keyboard cover 16 in the first position or in the usage mode 2. For example, when the user wants to reset to a state, the user can simply reset the cover without closing the power supply by simply closing the lid for a short time.
When the power supply end ready state is continued for a predetermined time, the process proceeds to S99 to execute the power supply end process.
When the power plug is inserted into the outlet and the hidden power switch is turned on or when a power switch (not shown) linked to the operation of opening the keyboard cover 16 is turned on, a power control unit (not shown) is activated, Power is supplied to the hardware configuration shown in FIG. In step S99, the power control unit cuts off the power supply to the hardware configuration.

  In the case of the second specification in which the setting data whose setting has been changed in S94 in the use mode 2 is stored at the end of the power supply, the current setting state written in the current buffer is stored in the save buffer in S97 described above. In S99, the setting data set to backup ON among the saved setting data in S99 may be written into the backup ROM (flash ROM) 64 or the like.

  In the above description, the setting data of a specific instrument tone color is not backed up even when the harpsichord is selected in S87, and is initially set to the grand piano in S85 when the power is turned on again. However, if the setting data of a specific instrument tone is also set to backup ON, the backup is performed, and the backup is changed to be initialized as a specific instrument tone when the power is turned on again. May be.

FIG. 6B is a flowchart illustrating an example of a process for determining the passage of time in S98 of FIG.
This flowchart is activated at a predetermined interrupt time interval, and in S101, if the power end preparation mode, that is, PW = 0, the process proceeds to S102, and the time elapse parameter T is incremented by 1 and the process ends. The value of T is set to 0 at the initial setting of S81. In S98, the value of T corresponding to the predetermined time may be compared with the current value of T that is increased by the interrupt process of FIG.

In the above description, the specific instrument tone color setting using the specific instrument tone color designation switch can be executed only in the use mode 1.
However, even in the use mode 2, a specific instrument tone color can be set in advance by providing a specific instrument tone color designation switch and operating it, or operating an existing operator. May be changed. The specific instrument tone color is set when the usage mode 2 is changed to the usage mode 1 with the power on.
In use mode 2, in order to immediately change the current instrument tone color to a specific instrument tone color, an existing instrument tone color designating operator for designating an instrument tone color corresponding to the specific instrument tone color may be operated. In addition, in the use mode 2, if the specific instrument tone color designation switch is operated, the process may be changed so that the current instrument tone color becomes the specific instrument tone color immediately.

FIG. 7 is a flowchart showing an example in which the operation of the embodiment of the present application shown in FIG. 6 is partially changed.
That is, in S82 of FIG. 6, this is a change example of the processing in the use mode 1 when the keyboard cover 16 is at the intermediate position.
In a user-registerable electronic keyboard instrument, at the time of user registration (including registration update), a specific instrument tone color is registered and set in advance, and the registered specific instrument tone color is set as a specific instrument tone color. .

In S111, if PW = 1 already, the process immediately proceeds to S89 in FIG. 6. If PW = 1 is not satisfied, PW = 1 is set in S112.
In S113, it is determined whether or not a specific instrument tone color has been designated (hereinafter referred to as "user designation") during user registration (this processing step is not shown).
When there is no user designation, in S114, the specific instrument tone color designation data is set as grand piano designation data (first specific instrument tone color designation data), and the process proceeds to S116.

On the other hand, in S113, if there is a user designation at the time of user registration, the process proceeds to S115, and a specific instrument tone is designated for the designated user name (for example, the user is recognized and the user name is designated in S81 of FIG. 6). The instrument tone color registered as the designation data is set as the specific instrument tone color designation data, and the process proceeds to S116.
In S116, the specific instrument tone color setting data set in S114 or S115 described above is set as the current instrument tone color setting data. Further, the standard volume setting data is set as the current volume setting data, and all the current automatic function setting data are turned off.
When a single user uses an electronic keyboard instrument, user registration may be omitted or user identification may be omitted.

According to this modification, even if there is no specific instrument tone color selection switch, a specific instrument tone color can be set.
When a plurality of users can be registered in the electronic keyboard instrument, various setting data are backed up for each user in S94 or S99, and when the power is turned on again, the power-on operation is performed in S81 of FIG. Initial processing can be performed for each user by performing processing for identifying the user and restoring the backup data registered for the user who activated the power source.

If the user changes after power-on and a new user registers as a user in S94 of FIG. 6, the current setting data is backed up as new user setting data in the backup process.
For user identification, a user ID may be set, and when the power is turned on, the user ID may be input and collated with the set ID in S81. Alternatively, a specific identification device for checking a fingerprint pattern or a vein pattern is attached to a specific part of the instrument body, for example, a hidden power switch or the vicinity thereof, a grip part 29 of the keyboard lid hanging piece 28 or the vicinity thereof, and registered. The user can be identified by collating with the personal pattern.

A mode in which a specific instrument tone color is set using a switch for setting a specific instrument tone color as in the processing of S83 to S88 in FIG. 6 is referred to as a first specific instrument tone color setting mode, and S111 in FIG. A mode for setting a specific instrument tone color set by user registration as in the process of S116 is set as a second specific instrument tone color setting mode, and the specific instrument tone color setting unit 2 shown in FIG. Any one specific instrument tone color setting mode may be set in advance by mode selection, and a specific instrument tone color may be set.
Further, any specific musical instrument tone color setting mode may be set. In this case, the setting made last may be validated, or the setting in one of the specific instrument tone color setting modes may be prioritized.

FIG. 8 is a right sectional view for explaining the structure of another embodiment of the present invention.
On the premise of the structure of the grand piano, an open / close lid is provided, and the upper front of the instrument body is shown.
The musical instrument main body 121 is provided with a shelf plate (bottom plate) 123, a mouth bar 124, and a top plate 125 between left and right side plates 122. The rear of the top plate 125 is covered with a triangular roof lid 126. A keyboard unit 127 with a hammer mechanism is placed on the shelf 123, and the keyboard lid main part 128 with the lid closed is covered above the keyboard unit 127. The keyboard lid main part 128 and the keyboard lid hanging piece 129 constitute a keyboard lid.

A keyboard lid hanging piece 124 is attached to the front of the keyboard lid 128 by hinge coupling (not shown), and the pivoting tip portion 130a of the front plate 130 is coupled to the rear of the keyboard lid 128 via a keyboard lid pivoting fulcrum 131. ing. Further, the front plate 130 is coupled to a mounting bracket (not shown) fixed to the side plate 122 by a front plate rotation fulcrum 132 and is rotatably attached to the side plate 122.
Reference numeral 133 denotes an operation panel unit for an electronic musical instrument, which is arranged on the rear side of the keyboard arrangement of the keyboard unit 127. A plurality of electrical components 134 such as a setting operator and a display panel are arranged in the operation panel unit. Reference numeral 135 denotes a printed circuit board. P is a rotation fulcrum portion when the keyboard lid hanging piece 129 and the keyboard lid main portion 128 are pivotally connected by a hinge.

FIG. 8A shows a state in which the keyboard lid 128 is closed. When the keyboard lid hanging piece 129 is lifted up, the keyboard lid 128 is pushed up around the keyboard lid rotation fulcrum 131, and the keyboard lid hanging piece 129, the keyboard lid 128, and the front plate 130 are overlapped, as shown in FIG. As shown in FIG. The front lid 130 is in the same position as in FIG.
At this time, the keyboard surface of the keyboard unit 127 is opened, and the appearance of a natural keyboard instrument is exhibited. This time is the first use state already described, and is a use state in which a specific instrument tone is played.

  Further, when the front plate 130 is pushed backward together with the keyboard lid hanging piece 129, the keyboard lid 128, and the front plate 130 around the front plate rotation fulcrum 132, the keyboard lid 128 as shown in FIG. The fully open position. At this time, the operation panel unit 133 is also exposed. At this time, the second usage state described above is set, and all the timbres can be selected by the operator on the operation panel unit 133, so that the timbre is used in an arbitrary instrument timbre.

The operations of the flowcharts shown in FIGS. 6 and 7 can also be performed in this embodiment. Therefore, when returning from the state of FIG. 8C to the intermediate position of FIG. 8B again, even if a tone such as brass or guitar is set in FIG. The instrument tone is reset.
Further, when the cover is temporarily closed as shown in FIG. 8A, the initial setting state is reset.

Similarly to the embodiment shown in FIG. 2, when the specific instrument tone color designation switch is provided, it may be provided on the member exposed in the first use state.
Since the operation panel portion 133 has an appropriate inclination and shape, the stacked keyboard lid hanging piece 129, keyboard lid 128, and front plate 130 are changed from the state shown in FIG. 8B to the state shown in FIG. 8C. During the rotation, the electric parts 134 are not hit.
Also in this embodiment, a partition part 136 substantially the same as the partition part 24 shown in FIGS. 2 and 3 may be provided, and the partition part 136 may be used as a visual display part for key press guidance.

The locking mechanism for stably holding the keyboard lid 128 and the front plate 130 in the state shown in FIGS. 8A to 8C is, for example, the keyboard lid rotation fulcrum 131 and the front plate rotation fulcrum 132. It is only necessary to provide a structure in which one protrusion fits into the other recess at a specific rotation angle.
In addition, the fact that the keyboard lid 128 is opened in FIG. 8A and the keyboard lid 128 is in the position shown in FIGS. 8B and 8C is, for example, provided with a switch in the locking mechanism described above. do it.
Although it is not assumed to be used in a transitional position that is not in any of the states of FIG. 8A to FIG. 8C, after the keyboard lid 128 is opened, the state of FIG. As long as this is not the case, the second usage mode may be assigned.

FIG. 9 is a perspective view for explaining still another embodiment of the present invention.
In this embodiment, the opening / closing lid 143 covers the operation panel portion 142 located on the upper rear surface of the keyboard portion 141 (the illustration of the white key and the black key is omitted) when the lid is closed (shown). The keyboard part 141 is not covered.
On the operation panel 142, an instrument tone color designating operator (not shown, for example, a switch or numeric key switch similar to 221 in FIG. 3) and other operators (FIG. 3) are provided for setting an arbitrary instrument tone color. In addition, an operation element (not shown) such as a master volume for volume control is provided.

In this embodiment, when the open / close lid 143 is closed, the operation mode 1 is set, and the appearance of the natural keyboard instrument is presented, so that the pianist does not feel uncomfortable in appearance, The keyboard performance is unchanged.
That is, when the lid of the open / close lid 142 is closed, the operation panel unit 142 can only be seen on the front side surface (shown in black in the drawing), and various operators on the upper surface cannot be seen. The power switch is also hidden.
On the other hand, when the open / close lid 142 is opened, the operation panel unit 142 can be seen in the use mode 2 and can be set by using various operators on the operation panel unit 142. The keyboard performance is similar to that of a conventional electronic keyboard instrument. do.

On the lower surface of the musical instrument main body 140, a support body 150 including three leg bodies 151, 152, and 153 is connected and fixed at three locations. The rear center leg 153 has three pedals 154, and has stable support portions 153a and 153b extending from the pedal 154 in the key arrangement direction.
As the opening / closing lid 143 and its receiving portion, the lid sliding mechanism of the lid opening / closing device 36 shown in FIG.

The hardware configuration in this embodiment is the same as that shown in FIG.
FIG. 10 is a flowchart for explaining the operation of the embodiment shown in FIG.
Since the flowchart shown in FIG. 6 is partly changed, only a part is shown, and the same processing is omitted from the illustration, and the flowchart shown in FIG. 6 is used. In addition, also in FIG. 10, the same step number is attached | subjected to the step similar to FIG.

In this embodiment, the keyboard performance with the use mode 1 when the opening / closing lid 143 is closed can be performed.
Therefore, the control program is started when the power plug of this electronic keyboard instrument is inserted into the outlet, or when the hidden power switch (mechanical switch) is turned on after the power plug is inserted into the outlet. That's fine.
In S81, initial setting at power-on is performed.
In S161, it is detected whether the opening / closing lid 143 is in the closed position (the state shown in FIG. 9) or the fully opened position where the operation panel unit 142 is exposed. If it is in a transitional position until it is fully opened, it may be regarded as a closed position, but the determination process in step S161 may be repeated to wait until it reaches either the closed position or the fully open position.

First, when the lid position is the closed position, the process proceeds to S95, and it is determined whether or not the power supply termination preparation is in progress (PW = 0). If so, the process proceeds to S98 in FIG.
In S162, it is determined whether or not a power-off operation has been performed. Here, the power-off operation is executed by the sensor switch 144, for example. It is assumed that a power-off operation is performed depending on whether a finger approaches or touches the sensor switch 144.

If there is a power-off operation, the process proceeds to S96 in FIG. 6 to set PW = 0, and thereafter, the power-end processing of S97 to S99 is executed to turn off the power. If the predetermined time has not elapsed in S98, the process returns to S161 in FIG. 10, and the process proceeds from S95 to S98.
On the other hand, if there is no power-off operation, the process proceeds to S83 shown in FIG. 6, and the performance in the use mode 1 (natural keyboard instrument tone) shown in S84 to S90 becomes possible.
Also, in S161, if the lid position is in the fully open position, the process proceeds to S91 shown in FIG. 6, and the use mode 2 shown in S91 to S94, S89, and S90 (the initial setting at the time of power activation is the same as the conventional case). It is possible to perform a keyboard performance using an instrument tone color or an instrument tone color set or changed by an instrument tone color designation operator on the operation panel unit.
When the open / close lid 143 is fully opened, the power is not turned off unless the hidden power switch is turned off. Therefore, when the user finishes playing the keyboard, it can be expected that the user naturally brings the open / close lid 143 into the closed state. As a result, when the power is turned on again, the keyboard performance can be performed as the use mode 1 as it is.

Here, the description of the sensor switch 144 will be supplemented. The sensor switch 144 is, for example, the following non-contact sensor.
A non-contact sensor (for example, a capacitance change detection type sensor) is disposed in the region of the illustrated sensor switch 144, and the power is turned off depending on whether a finger approaches or touches this region. The sensor switch 144 may be a mechanical contact switch provided inside a flexible surface material so as not to stand out, instead of a non-contact sensor.

Further, by operating this sensor switch 144, the power may be turned on while the power plug of the electronic keyboard instrument is inserted into the outlet.
. In that case, for example, three non-contact sensors (mechanical contact switches) are arranged side by side. At least, the power is turned off by bringing two fingers close to or touching two non-contact sensors (mechanical contact switches) at both ends thereof. On the other hand, the power is turned on by bringing one finger close to or touching only the central non-contact sensor (mechanical contact switch).
If the manufacturer's name of the electronic keyboard instrument is printed on the surface of the sensor switch 144, the position of the sensor switch 144 and the position of each non-contact sensor (mechanical contact switch) can be understood well. . If the surface of the sensor switch 144 is opaque or translucent so that the non-contact sensor (mechanical contact switch) is not visible or difficult to see from the outside, the manufacturer's name will be printed on the sensor switch 144. It becomes a marker.

When the hidden power switch is turned on while the power plug is inserted into the outlet or after the power plug is inserted into the outlet, the power control unit (not shown) is activated, and the hardware shown in FIG. Supply power to the configuration. This power supply control unit cuts off the power supply to the hardware configuration in S99 of FIG.
Further, when the power is turned on / off with the sensor switch 144 being inserted into the outlet, the power control unit is activated while the power plug is inserted into the outlet. The on / off operation of the sensor switch 144 is monitored, and when the sensor switch 144 is turned on, power may be supplied to the hardware configuration shown in FIG.

FIG. 7 described above is obtained by changing a part of the processing shown in FIG. Similarly, in FIG. 10, part of the processing may be changed as in FIG. 7.
In the above description, three specific examples have been shown as the structure of the keyboard instrument body, but the structure is not limited to these structures. Depending on the structure of the keyboard instrument body, the structure of the opening / closing lid is variously changed.

It is a block diagram explaining the functional structure of the electronic keyboard musical instrument which is one Embodiment of this invention. It is right side sectional drawing for demonstrating the structure of one Embodiment of this invention.
